Description

Needle injector for insulin syringe

The present invention relates to the technical field of a needle unloading device for an insulin syringe, and more particularly to a needle unloading device for an insulin syringe which can make the needle of an insulin syringe more convenient, quick and safe.

Referring to FIG. 1 , the structure of a general insulin syringe 10 (commonly known as a stylus) is mainly provided with a screwing portion 12 at the head end of a syringe 11 and a needle holder 14 on a needle 13 . The internal thread can be screwed to the screw portion 12 for injection. After the injection, the insulin syringe 10 needs to first put a sleeve 15 on the needle portion of the needle 13, and then the original packaging sleeve 16 is sleeved on the needle sleeve 15 and the needle holder 14 of the needle 13. Then, the needle holder 14 is then unscrewed from the syringe 11 for recycling.

However, during the process of removing the needle 13, when the needle cover 15 is put back on the needle portion of the needle 13, the needle 13 is easily contacted because the user's hand needs to be in close contact with the needle 13. The danger, especially for users with poor eyesight, is the case of needle sticking. Further, since the needle hub 14 and the syringe 11 are screwed to each other, when the needle 13 is detached from the syringe 11 by both hands, it is not easy to apply force, and it is also required to be applied. Big power to rotate The needle seat 14 can be disassembled, so it is also very laborious, time consuming and inconvenient when unloading the needle.

The main purpose of this creation is to solve the problem that the current insulin syringe is very close to the needle when the needle is removed, which is easy to cause needle sticking, and is very laborious, time consuming and inconvenient when unloading the needle.

The needle unloading device of the insulin syringe described in the present invention is mainly for conveniently, quickly and safely disassembling the needle of an insulin syringe from the syringe. Wherein, the needle has a needle seat for screwing on the syringe. The needle removing device of the insulin syringe comprises a container and a needle removing cover. The container has a chamber and an opening in communication with the chamber. The bottom of the unloading cap has a joint for detachably coupling to the opening of the container, and the top surface of the unloading cap has a needle insertion hole penetrating into the chamber for insertion of the needle of the insulin syringe, The hole of the needle removing hole is larger than the outer diameter of the needle seat of the needle, so that the insulin syringe is slightly inclined by an angle, so that the two opposite outer side walls of the needle seat are clamped on the hole wall of the needle removing hole.

The needle unloading device of the insulin syringe provided by the present invention, after inserting the needle of the insulin syringe into the unloading hole, tilting the insulin syringe slightly to one side to make the opposite outer side wall of the needle seat of the needle The needle can be reversely rotated on the wall of the hole of the unloading hole to save the needle and the needle is unscrewed from the barrel, so that the needle falls into the chamber of the container. collect. In particular, it does not need to perform the action of returning the sleeve when the needle is disassembled, and the user's hand does not approach or contact the needle at all, so that it can effectively prevent the use of the needle. The risk of needle sticking occurs when the needle is removed and recovered. Therefore, the operation is very simple, convenient and fast, especially at a very low cost.

Referring to Figures 1 to 5, the needle removing device for the insulin syringe of the present invention includes a container 20 and a needle removing cover 30, wherein:

The container 20 has a chamber 21 and an opening 22 communicating with the chamber 21. In the present creation, the container 20 may be a bottle of other common and readily available bottles such as a bottle.

The unloading cap 30 has a joint portion 31 for detachably coupling to the opening 22 of the container 20, and the top surface of the unloading cap 30 has a needle releasing hole 32 extending through the chamber 21. The needle 13 of the insulin syringe 10 is inserted, and the aperture of the needle removing hole 32 is slightly larger than the outer diameter of the needle seat 14 of the needle 13, so that the insulin syringe 10 is slightly inclined by an angle to make the opposite sides of the needle holder 14 The wall card is in the unloading The upper and lower edges of the hole wall of the pinhole 32.

In the embodiment, the joint portion 31 includes a belt 33, a positioning sleeve 34 and a locking member 35. The bundle 33 is provided with a plurality of long inclined holes 330 penetratingly spaced apart. The positioning sleeve 34 is coupled to one end of the strap 33 and is permeable to the other end of the strap 33. The locking member 35 is rotatably coupled to the positioning sleeve 34 and has a threaded tooth 350 for engaging with the plurality of long inclined holes 330. The locking member 35 has a protruding end at the end of the locking member 35. 34 one of the external force applying sheets 351. Thus, the diameter of the band 33 can be adjusted by rotating the locking member 35 by the force applying piece 351 so that it can be applied to the container 20 which is tightened to the caliber of the various openings 22.

In Fig. 5, it can be seen that when the needle 13 of the insulin syringe 10 is inserted into the unloading hole 32, the insulin syringe 10 is tilted slightly to one side, so that the needle holder 14 of the needle 13 can be made. The two opposite outer sidewalls are latched on the upper and lower edges of the hole wall of the unloading hole 32. At this time, the needle 13 can be unscrewed from the syringe 11 by rotating the syringe 11 in reverse. The needle 13 is caused to fall into the chamber 21 of the container 20. When the number of the needles 13 recovered in the chamber 21 reaches a certain amount, the opening 22 of the container 20 can be closed by a lid (or the original lid of the container 20) to facilitate transportation and recycling.

Referring to FIG. 6, it is another embodiment of the unloading hole 32 of the needle removing device of the insulin syringe of the present invention, wherein the hole wall of the unloading hole 32 is provided with at least one convexity. Part 320. The convex portion 320 can further increase the locking effect on the opposite outer sidewalls of the hub 14.

Please refer to FIG. 7 , which is another embodiment of the needle unloading device of the insulin syringe of the present invention, and the structure thereof is substantially the same as that of the above embodiment, and the difference lies only in the joint portion of the needle removing cover 30 of the embodiment. 31 is an internal thread 36 provided on one of the inner side walls of the unloading cap 30. The needle release cover 30 is slidably disposed on the container 20 having the corresponding external thread 23 by the internal thread 36.

The needle unloading device of the insulin syringe provided by the present invention is such that the needle 13 of the insulin syringe 10 is inserted into the needle removing hole 32, and then the insulin syringe 10 is tilted slightly to one side to make the needle seat 14 of the needle 13 The two opposite outer side walls are clamped on the hole wall of the unloading hole 32, and the needle barrel 11 can be reversely rotated to save the needle 13 from the needle barrel 11 by mechanical force and rapid removal. 13 is collected into the chamber 21 of the container 20 for collection. In particular, when the needle 13 is disassembled, there is no need to perform the action of returning the sleeve, and the user's hand does not approach or contact the needle 13 at all, so that the needle can be effectively prevented from being broken when the user removes and recovers the needle 13. Dangerous. Therefore, the operation is very simple, convenient and fast, especially at a very low cost.
